But now we have identified issues and there are reproducers available (e.g. on 
https://github.com/llvm/llvm-project/issues/62719). Keeping it in main is just 
disruptive and risks making reverting harder (it's already not a clean revert). 
I think the policy of reverting back to green still applies.
